The use of the word "accents" over five chapters caught my attention. I'm not accustomed to it being used as a synonym for "tone of voice," but I like it.
I've listed all as follows (haven't yet figured out how to place selected words in bold):
"Wholly inattentive to her sister's feelings, Lydia flew about the house in restless ecstacy, calling for every one's congratulations, and laughing and talking with more violence than ever; whilst the luckless Kitty continued in the parlour repining at her fate in terms as unreasonable as her accent was peevish.
"Wickham's alarm now appeared in a heightened complexion and agitated look; for a few minutes he was silent, till, shaking off his embarrassment, he turned to her again, and said in the gentlest of accents --"
[Mr. Darcy]" Nor did he seem much more at ease: when he spoke, his accent had none of its usual sedateness; and he repeated his enquiries as to the time of her having left Longbourn, and of her stay in Derbyshire, so often, and in so hurried a way, as plainly spoke the distraction of his thoughts."
[Elizabeth observing Mr. Darcy upon introduction to Georgiana] "It was not often that she could turn her eyes on Mr. Darcy himself; but, whenever she did catch a glimpse, she saw an expression of general complaisance, and in all that he said she heard an accent so far removed from hauteur or disdain of his companions,as convinced..."
[Elizabeth asking servant to fetch Gardiners] "Calling back the servant, therefore, she commissioned him, though in so breathless an accent as made her almost unintelligible, to fetch his master and mistress home instantly."
(Kitty and Mary] The faces of both, however, were tolerably calm; and no change was visible in either, except that the loss of her favourite sister, or the anger which she had herself incurred in the business, had given something more of fretfulness than usual to the accents of Kitty.
